Introduction Integrated System for Protection of Birds (ISPB) includes 114 wind turbines, 95 of which are within the Kaliakra SPA BG0002051 and 19 are in the areas adjacent to the protected zone. The ornithological monitoring of ISPB is a complex study assigned by the Wind farms, located in Kaliakra SPA BG0002051- AES Geo Energy Ltd., Kaliakra Wind Power AD, Degrets OOD, Disib OOD, Windex OOD, Long Man Invest OOD, Long Man Energy OOD, Zevs Bonus OOD, Vertikal-Petkov & Sie SD, Wind Park East EOOD, Wind Park Kavarna West EOOD, Millennium Group OOD in 2018. The ISPB consists of a combination of radar observations and meteorological data, integrated with field visual observations, which jointly used are essential for the accurate risk assessment and ensure that appropriate action is taken immediately to avoid collision risk. So far as potential adverse impacts of turbine collisions on birds, a Turbine Shutdown System is deployed supported by an Early Warning System. The monitoring studies are based on the requirements of basic normative and methodological documents as follows: Environmental Protection Act, Biological Diversity Act, Bulgarian Red Data Book, Directive 92/43/EEC for habitats and species, and Directive 2009/147/EC on the conservation of wild birds, Protected Areas Act and Order RD-94 of 15.02.2018 of the Minister of Environment and Waters. Best international practices are also incorporated (T- PVS/Inf (2013) 15: https://rm.coe.int/1680746245). Detailed information on the scope, technical rules and monitoring procedures are publicly available at a dedicated website https://kaliakrabirdmonitoring.eu/.

In order to provide objective data for the bird risk assessment, this summary presents activities and results of the monitoring in 2018. The activities were supervised and coordinated by Prof. Dr. Pavel Zehtindjiev - Ornithologist with over 25 years of research in ornithology; over 85 scientific publications in international ornithological journals; member of European Ornithologists Union and several other conservation organisations; winner of the Revolutionary Discovery Award for Ornithology of an American Ornithological Society in 2016 – The Cooper Ornithological Society; 10 years of experience in impact monitoring of wind turbines on breeding, migrating and wintering bird species in the region of Kaliakra.

Three types of radars integrated into the ISPB were used for monitoring and prevention of bird collisions: Bird Scan MS1 The radar collects quantitative data and provides information about Migration Traffic Rate of birds through a specific sector where the fixed beam of the radar is directed (Figure 1). The quality of the data deepens on the distance to the birds and to the size of the migrating birds. In the case of ISPB the maximum distance we have used the Bird Scan MS1 radar is 10 km beam directed from west to east across the main migratory front of seasonal migrations. The data obtained by this radar system allow crude identification of ecological types of birds: for example, passerines, swifts, waders and large birds. The radar data do not allow quantification of bird migration for every bird species observed in the ISPB territory and therefore do not allow any comparison with visual observations. These data are not used for quantification and analysis of the characteristics of migration.

Deltatrack Radar System This radar is a tracking radar system which allows detection of a single target or group of targets and tracking of their movements in a range of around 5 km (Figure 1). It is used in the monitoring as a real time tool for the tracking of already (visually) identified bird targets in the ISPB territory. The radar is not applicable for quantitative analysis of bird migration.

Radar System Robin This is a 3D radar system constructed for detection and tracking of moving targets in air volume of around 10 km3 (https://www.youtube.com/watch?v=-Kb70clGHOQ&t=8s) (Figure 1). It is a real time tool for tracking of moving targets and in combination with visual observations in the field provides highly reliable data on the distance as well altitudes of birds already detected and identified by the field ornithologists. This radar does not provide quantitative data of migration at a species level because it does not allow species identification. All three radar systems have been used as tools to assist field observations, detection of potential ingresses, and real time tracking of birds after visual observation through the ISPB during the period of monitoring. All quantitative data and analysis of recorded bird numbers are based on the only possible quantification of bird migration of different bird species – the visual observations in the field. Locations of field observation points are presented in Figure 1. Detailed descriptions of the technical characteristics of the three radar systems integrated within the ISPB are presented on the web site: https://kaliakrabirdmonitoring.eu/.

Results

Spring migration During the spring monitoring, observations were made during all 92 days of the season, with registered migratory soaring birds being detected over 70 % of the time. For the survey period (March 15 - May 15), a total of 1560 migratory and resident birds (Table 1) were registered.

Figure 3. Dynamics of the spring migration of birds in the ISPB territory based on visual observations during the period 15 March - 15 May 2018 The variations in bird numbers were substantial (Figure 3). The low number of migrating birds through the study area, because of the relatively low prevalence of westerly winds in this season, did not allow for an in-depth statistical analysis of the number of birds according to wind direction. Migratory birds were poorly represented during the spring migration period in the surveyed territory. Of the total of 1560 birds registered in the course of the study, 1519 individuals were identified to species. The species and number of birds recorded during spring migration is shown in Table 2.

The most numerous in spring in the region were common cormorants (Phalacrocorax carbo), white pelicans (Pelecanus onocrotalus) and some birds of prey – Common buzzards (Buteo buteo), Red-footed falcon (Falco vespertinus), Common kestrels (Falco tinnunculus) and Marsh harriers (Circus aeruginosus) (Table 2). In the spring of 2018, a total of 81 White storks (Ciconia ciconia) passed over the surveyed territory. The European nesting population of the White stork is estimated to be between 180,000 and 220,000 pairs, with about 80 % of the species migrating along the wider western region, which also covers a part of north-eastern Bulgaria. Compared to these values, White storks flying over the Kaliakra area, substantially east of the main migratory path of White storks along the western Black Sea migration corridor, were an insignificant proportion (0.02%) of the population. According to Shurulinkov et al. (2011), an estimate of the total population of White stork in SE Bulgaria flying along Via Pontica in spring was 23,358 individuals in their study period. In this respect our observations confirm the low significance of the territory of Kaliakra as part of the migratory corridor for spring migrating white storks along the Via Pontica component of the larger flyway. Similar numbers of two crane species - Common and Demoiselle cranes - were seen. Common cranes (Grus grus) were recorded for three days in March, and Demoiselle cranes (G. virgo) were observed over seven days in April and May. There was remarkable behaviour involving a pair of Demoiselle cranes which stayed in the ISPB area for nearly 30 days between April and May. A pair of these beautiful birds used a temporary pond of surface water for feeding within the territory without showing any apparent signs of fear of the nearby wind turbines. As a result of the systematic observations carried out during the whole period of the spring migration a total of 11 stops of individual turbines, groups of turbines or entire wind farms in the territory covered by ISPB were undertaken. Detailed information on the duration of these stops is given in Table 3.

According to previously performed carcass removal and searcher efficiency tests during autumn migration and in winter at SNWF, this search regime of weekly searches provides for a cost-effective method, which can also be calibrated, to discover any bird strike fatalities which may be of concern. Hence a frequency of four searches per month under every turbine allows estimation of the mortality of the birds from a collision with the turbines in the ISPB.

Five intact bodies of birds were documented during the 1024 searches under individual turbines during the 2018 spring migration of birds in ISPB territory. (Table 5). There were six records of feathers or single feather. Such findings of single feathers as well as groups of body feathers are often remains of hunting and feeding of raptor species in the wind farms.

There was no recorded case of collision with the turbines of any target bird species for the period of TSS application in ISPB during the monitoring in spring 2018.

Conclusions

During the monitoring, there were no apparent changes in the main characteristics of the ornithofauna typical for the spring migration in the whole country and the specific characteristics of the species composition and phenology of bird migration in NE Bulgaria. The results of the monitoring confirmed the relatively low importance of the ISPB territory for migratory birds in spring and the absence of negative influence of the operating wind farms on bird populations during their spring migration. The migration periods, the species composition, the dynamics in number of birds, the daily activity, the height of the flights, as well as the feeding, resting and roost sites of the flying birds passing through the area indicated the absence of a barrier effect of the 114 wind turbines. The data presented in this report confirmed the absence of any adverse impact on sensitive bird species of the order Ciconiiformes, Pelecaniformes, Falconiformes, Gruiformes using migratory ascending air flows (thermals) for movement over long distances. All these species were found to occasionally cross the study site, and their observed behaviour in respect to wind turbines did not indicate major changes which would impact on the energetics of these species during daily movements. The quantitative characteristics of bird migration in the ISPB area during spring 2018, and the absence of mortality among the target bird species allows a continued conclusion that 114 wind turbines covered by ISPB do not present a risk of adverse impact to migratory birds. The application of the ISPB’s safeguards potentially was and can be an ongoing contributory part of the minimal risk posed to birds from wind farms in the Kaliakra region.

Autumn migration

During the autumn monitoring, observations were made during all 92 days of the season in 2018 (01.08 - 31.10.2018). There were a total of 16973 birds of 53 species. 10 ECOPRAXIS ЕООD ISPB – Annual summary 2018

The number of birds in the ISPB study area apparently depended on the direction of the wind in autumn 2018. Of the 10 peak days with intense migratory flights of birds: in nine, westerly winds prevailed, and in only one day with a relatively high number of registered migrants, the wind direction was eastern (Figure 5). The recorded number of individuals according to species during autumn migration is shown in Table 6.

The most numerous migrating birds in the autumn of 2018 in the region were Common buzzards (Buteo buteo) and White pelicans (Pelecanus onocrotalus) with over 2,000 individuals of each species (Table 6). Bee-eaters (Merops apiaster) were also numerous with over 2,900 individuals registered during the autumn migration period. Third, with a little more than 1,000 individuals were Barn swallow (Hirundo rustica), Calandra lark (Melanocorypha calandra), and Wood pigeon (Columba palumbus), flocks of which were registered feeding in the ISPB during the autumn migration in 2018. As a result of the simultaneous observations of five constantly attended observation points with assistance from three radar systems (Figure 1) during the whole period of the autumn migration, a total of 7 stops of single turbines, groups of turbines in the territory of SNWF. The stop orders given to the engineers on duty were executed in a timely manner, thus avoiding any collision risk of birds passing through the territory. Detailed information on the duration of these stops is given in Table 7.

As a result of 1409 searches under 114 individual turbines between 1 August and 31 October 2018 a total of eight dead birds of six species were identified as being fatalities through collision (Table 9). Individuals found as collision victims did not involve the target ISPB species. Table 9. Victims of collision with turbines during the autumn migration period in 2018.

Conclusions During the monitoring, there were no apparent changes in the main characteristics of the ornithofauna typical for the autumn migration in the whole country and the specific characteristics of the species composition and phenology of bird migration in NE Bulgaria. The results of the monitoring confirmed the relatively low importance of the ISPB territory for the migatory birds in autumn and the absence of negative influence of the operating wind farms on bird populations passing through the ISPB during their autumn migration. The migration periods, the species composition, the dynamics in number of birds, the daily activity, the elevation of flights, as well as the feeding, resting and roost sites of the flying birds passing through the area indicated the absence of a barrier effect of the 114 wind turbines covered by ISPB in autumn migration period. The data presented in this report confirmed the absence of impact on sensitive bird species of order Ciconiiformes, Pelecaniformes, Falconiformes, Gruiformes using migratory upward airflows (thermals) to move (soaring) over long distances in autumn migration period. All these species were found during the study to cross the site using suitable habitats without the need to increase their energy losses in their daily movements and to change their migratory strategy in the period of autumn mugration. The quantitative characteristics of bird migration in the ISPB area during autumn 2018, and the absence of mortality among the target bird species allows a continued conclusion that the studied wind farms do not present a risk of adverse impact to migratory birds. The application of the ISPB’s safeguards potentially was and can be an ongoing contributory part of the minimal risk posed to birds from wind farms in the Kaliakra region. A study of wintering geese in the ISPB was carried out in the period of 01 December 2018 to 28 February 2019. The results are reported in the respective seasonal report. A summary will be included in the annual report for 2019.
